Application filed. Decemberm, 1924. serial no. 754.953.

" liably support, pieces of lumber in accurate relative position for the formation of clean cut cask heads.

M A'still further object is to provide a work holder for supporting the severalpieces of lumber from which a cask head is made and 1 to permit relative shifting of one piece of the lumber to permit proper positioning of the cutting saw in the first instance.

it islikewise an object to provide a novel take-off whereby current is continually fed to [a motor which'drives arotary saw.

Otherv objects will be in part obvious and in part pointed out hereinafter.

In order that the lnventlon and its mode ofoperation may be readily understood by persons skilled in the art, I have in the accompanying illustrative drawings; and in the following detailed description based thereon set out one possible embodiment of the same.

Figurel is a side elevation of a complete ly assembledcask head cutter constructed in accordance Wltll my invention;

Figure 5 is a detail sectionshowing the spursor grippers; J i g Figure 6 is a detail viewashowingan aux- :iliary support which I associate with the main work holder;

Figure 7 is a detail elevatlon partially in sect1on showing the arrangement of the current take-off. I 7 a Figure 8 is a gtra mentary plan view of one of the sections s own in Figure 7 and c Figure is a detail sectional view showlars of each segment. h H 7 Hav ng more particular reference to the Another object is to provide a work holder'of simple construction" such as w ll respurs are adapted to engage the lower faces without the pointed upper ends for reasons which will be immediately pointed out. O'bing therelation of the drawings throughout which similar characters or reference designate similar parts, this mproved cask head cutter may be inner and outer colbroadly stated as comprising a main frame F (not completely shown),"a work holder having means for automatically positioning the work for cutting; a motor driven rotary saw adapted for circular movement around the periphery of the work holder, and mech anism for relievin'g-thework holder of the weight of the motor and associated partsto permit separation of the holder. and removal ,of the completely out cask head.

.lVorkho Z der 0? saw table.

The work holderor saw tablecomprises a disc-like base portion 10 which is preferably made up of heavy metal and is provided near its periphery witha set of circumferentiallyspacedopenings 11 in which are disposed spring pressed spurs 12'. These ofth'e strips of lumber L and movethem into snug engagement with the lower or inner face of the top clamp member, 13 of the work :holder to insure perfect cutting of cask heads Each spur consists of a body portion having a headed inner end 14 which engages a shou'lderformed in the opening 11, said head and'shoulder being yieldably intereengageable through the: action of an expansion coil spring 15 whose tension is variable through adjustment of a screwplug 16 as is clearly shown in Figures 4.- and Certain of these grippers are formed viously variation in the means for mounting the body portion may be resorted to.

At theibeginning of the sawing operation,

permit thesaw to obtaingasuitable start the central lstrip. pThisj is accomplished through provi'dingfthe baseportio'n 10 of the work holder with a pair of elongated alined diametricallydisposed slots 17 as shownin Figures 3 and 4:. Each of these p ll springs 21 as shown in Fi Borgia 1J0 saw supporting one? blocks to accomplishthe above stated operation a treadle 22 is depressed and tin-ouc a link connection with sprocket chain 2% or the l ke as illustrated n F1f2'lll6 2, this moyen1ent is readily effected. Thissprocket chain has its two ends secured to the conv'llecti lig ha r and has its intermediate portions carried over n roller which is supported from the base 10 and isassociated.

with the upper end of thejlink as clearly i'llu ed in Figure 4;. Flt is obvious that with downwa rd movement of the trealle 522 the lower portion ofthe chain will be moved downwardly. and consequently shift the gripping; hlockslS) radially and effect move- "merit orthecentral strip of lumber .0 per- ".t suitable posit on ng o i'a cutt ng saw,

Aft-timesit is desirableto provide additional. support for the edgeponjons of the strips of lumber fromwhich the cask heads are being; cut and forthis purpose I provide as shown in Figures 3 and6. at liary arms ic ,a e dia lreml Ve tical- V Mir-s l arin consists oi a pair oi spaced bars 27 wh'ichare slidable insockets formed in the base 10 and'whichcarry in their outer ends threaded nipples 28'by means of which the supportino bar 29 may he elevated.

As a means for penniting the cutt of large cask heads I provide a set of an: lierv rin e's 2.9 each of which is formed as indicated in dotted lines in Figure 5. It is ohvious that the provision of such ring's each .of whichis equipped withthe heretofore (lescrihed spurs, will permit formation or" varisizced heads. I

adjusau g mechanism.

This mechanism is associated with and. arranged above the work holder and consists of a hub 30 which is rotatable upon the lowcr end of a fixed tubular casing 3 1} whose upper end is bolted or connected "in some other manner to a headmember 32 as shown in Figu-re 1 of-the accompanying drawings. A rota-table collar is" mounted upon the Casi-115 131 at a point: spaced above the hub and s connected w th said hub by means of curved arms orbars 34 as clearly shown 1n Figure 1.. A hand rail 35, as shown in "Figures 1 and 2 is spaced from the medial .ran in Figure 2.

pulley 54 portions of the curved arms or bars 34 and connected therewith by means of short rods 36. this structure providing for unitary rotation of the hub 30, collar 83 and said arms 34min respect to the casing 31. A thrust bearing 37 is arranged between the lower --en( l-oi the hub 30 and the top clamp member 13 to .pport the weight of said hub and s associated therewith and allow for rotation upon the work holder.

A substantialr r Usuapcd slide menu her strud the arm 88. and mount an said motor and slide being; 7 the arm n d lockable at any point through adjustment of bolt 39 or the like ch :GS he suppouring, arm. Pairsor downwardly extending; brackired to theopposite longitudielectric motor movable u on ets 41 are secu nal faces otthe slide member and support he r lower ends a short shaft which rotatable by means of a d ven from a pulley mounted upon ectric motor shown in FigureQ. A pair of ss'wsis meal to the opposite end of the h V are partially enclosed in a arric. a pulley and 4o for'ohvious reasons. One saw 46 P .eater'diainetcr than the other saw 417 is designedto function, with the latter to form ai -double -hevel at the periphery of a cesikhead as illustrated in .thedeta'il View in Figure lhe outer end of the motor supporting arm :38 is connected to the hand by meansot stay rods 47 as indicated An e ectr c tale-oft device 4S-is associated with the upper portion of n casing {11 a shown in Fi we 1 and provides for continuous tro ling of electr c current to the saw driving; me or shall times. In order to provide "tor e' evation' ot the saw and parts fiscdly assoc ated therew th I arrange upon the head 32 one or morepulleys .49 over which a sprocket chain fitl s trained. one end seiun' connected to ears 5'1 carricdby a swiveling; ring 51 on the collar whilethe other end attac'hed toia block 52carried by a hand lever 5.3 ustrated in Figure 1.

Itis quite clear from the above that with the pz rts positioned as shown. in Figure 1, "the saw and associated elements may be an IN-U readily elevated through depress on of the lever 53, this lever movementserving to lift the collar 33, hub and simultaneously clamp member 13.

raise the remaining; elements which arecon- 'nected thereto. It is also apparentthat the elevation of theseparts will relieve the top clamp members 13 oi'jthe'weight' of said parts, such wveight being utilized to reliably clamp boards or the like'in the work holder during the sawing operation. In order to retain the saw in elevatedposition I provide a pivoted hook 563; engageable with a finger 57 carried by the operating lever 53 asrshownin Figure 1, said hook being mount-ed upon one of the curved arms 34.

The above operation having been com pleted it is now necessary to raise "the top clamp member 13 before the finished cask head can be removed from the work holder and in order to attain thisI provide a top clampliftingdevice. t 7

Top clamp lifting Janice;

This device cons sts in the provision of a relatively short shatt 53 within the hub 30' and casing 31 as shownin dotted lines in Figure 2 of the acc'on'ipanying drawings The lower end of" this' shaft- '58 is fixed to the top clamp member '13 through the arrangement of a flange plate 59 as shown and standard well known elements. 1 The upper end portion of the shaft 58 extends considerably above thehand rail to provide a suit-' able bearing. areato prevent slapgingof the parts during the operation period. The aforementioned casing .31 is slotted as shown at 60 to permit the a rrangeinentfof a transverse bolt or {key 61 whoseopposite ends carry blocks 62 to which a chain or chains 63 may be keyed; This chain or chains as inner end portionof the hand lever 64 as shownin Flgure 2, the intermediate port1ons of the chain or chains being trained over one or more pulleys 65 fixed to a collar 66 mounted upon the casing 31. The inner end of the hand lever 64 is pivoted to a collar 6? spaced below the slotted portion 60 of the casing 31 and it is obvious that with downward movement of said "lever the'shai't 58 will be elevated and carry with it the top Y Vith this operation it is clear that the finished cask head may be readily removed from ,the work holder.

3 With sutlicient downward movement of the lever 64 it will pass dead center and auto rnatically lock itself in such downward position with the result that the operator will be free to use both hands in completion of his work.

3 Operation.

The hand lever 53 is first depressed in order to raise the hub 30, the saw and other parts with the/ result that'- theshaft 58 {and top posit ons, it being stated. the case may be, have connection with the ,A. contact or take-off ring periphery of the inner collar 68 and is deremain in their original understood that the first named parts are vertically slidable on said shaft 58. The lever 64 is then depressed and eiiects vertical movement of the shaft 58 within the casing 31 and consequently sepaclamp member 13 rates the top clamp member 13 from the base portion 10 of the work holder. At this pointthe severalstrips of lumber to be employed in making up the cask head are artrated in Figure 3 of the accompanying. drawings, said strips being shown in 'dot and dash lines. The aforementioned levers 53 and 64lare lifted, the lever 64 being the first one, and thereby eflects a reliable clamp, in}: action upon the strips from which the rangled. upon the base portion 10 as illu$- p cask head is to be formed. 1 At this point theholder and saw must be adjusted to determ ne the dimensions of the cask head be J ing formed; Thisis accomplishedthrough Y aroundrthe work holder is GfieCtGCllhiOUgl).

the op'erators gripping of the hand rail and moving it circumferentially as isquite clear.

vWith completion oi the. sawing,v the first named actuation of the levers 53 and Gtis effected with the results ,as previously E Zectric current take-off.

In a structure such as heretofore set forth current must be continuously supplied to the electric motor and in order to insure against breaking of the circuit at any points I provide a take-cit which consists of pairs of innerand outer fibrecollars 68 and 69 respectively. Obviously any number of the pairs may comprisea set; the number being def pendent upon the type ofn'iotor to which the current is supphed.- The innorjtibre collar 68 is'fixed to a casing 31 which is provided rent conducting wiresi'flenter said casing.

o is fixed to the V with radial openings 71 through which cur-1 signed for electrical connection with a conductor 7 2 through the arrangeinentof a terminal post 74: whose inner end is attached to a block 75 having electrical connection to a said contact strip 73.

, The outer fibre insulating ring or collar has its inner wall channeled for the reception or" a spr ng ring 76 which can be made L circuits at any time.

I collar as shown.

of brass or any other ctiicient electrical can rent conducting material. This spring '76 shown in Figure 8 is connected toa terminal post 71" and is so bentas to alternately con- =tact with the take-off ring 78 and with the hianitestly, the construction shown is capable of considerable modni' atlon and such modification as may ran within the scope of my claims, I consider within the spirit of my invention.

I claim: 1. A work holder comprising a base, a top clamping member, devices carried by the base to uniforn'ily engage the work with the top clamping member, gripping devices slid ably carried by the base to grip the work, and means for laterally shitting said gripping devices to move a portion ofthe work.
